Fig. 1 is returned to, the other end 4b of axle 4 outside is provided with cup-shaped or bowl-shape resin cover plate 14.Resin cover plate 14 covers
And protect brush 9, rectifier 12 etc..Resin cover plate 14 is by fire-retardant rank material (UL standard V-0) or equivalent to fire proofing
Flame-retardant materials are formed.
Based on Fig. 4~Fig. 6, the resin cover plate 14 of present embodiment is illustrated.Fig. 5 is to represent resin cover plate from outside
Stereogram.Fig. 6 is to represent vertical with the resin cover plate behind axial direction and all separation integrallies upwardly extended from inner side
Body figure.
First, as shown in Fig. 4 and Fig. 6, the inner side of resin cover plate 14 is formed with lattice 15.The lattice 15 and resin cap
The other parts of plate 14 are formed and are integrated.Abreast prolong in the rotation axis direction of lattice 15 and the bearing of trend of axle 4, i.e. axle 4
Stretch.In other words, lattice 15 is erected on the inside of the end face of resin cover plate 14 with the direction of other end 4b to one end 4a from axle 4.
In addition, lattice 15 while axially extending also along circumferentially extending.Lattice 15 will be will have current potential
The mode spaced apart of the metal component of difference extends, specifically, as shown in Fig. 4 and Fig. 6, by radiator (+) 100 with dissipating
The mode that hot device (-) 120 separates extends.That is, lattice 15 between radiator (+) 100 and radiator (-) 120 to pass through
Mode circumferentially extend in (circumference relevant with the rotation of axle 4).In addition, circumferential be not strictly defined as same Radius
Circumference, also comprising following form：The shape of similar 120 opposed facing part of radiator (+) 100 and radiator (-),
Extended while the distance for leaving the rotation axis of axle 4 is changed (equivalent to diameter).Lattice 15 shown in Fig. 6
One example of the as above-mentioned form extended like that while the position of radial direction is changed.As shown in fig. 6, lattice 15
When the fore-and-aft direction of resin cover plate 14 is projected, there is curve shape.
The outside of resin cover plate 14 has concave shape or convex form, as present embodiment, in the example of hgure 5, has
Multiple concave shaped portion 14a.That is, concave shaped portion 14a is the phase with the main reference face i.e. uniform surface of resin cover plate 14 (last end face) 14b
To the part that relation is depression relation.In addition, the periphery and adjuster of the battery terminal covering part 14c on the outside of resin cover plate
Connector covering part 14d periphery is lower than the uniform surface 14b of resin cover plate 14, i.e. as shown in figure 5, above-mentioned concave shaped portion 14a
It is located at least in these battery terminal covering parts 14c periphery and adjuster connector covering part 14d periphery.Change speech
It, realizes the inner space of resin cover plate 14 on battery terminal covering part 14c and adjuster connector covering part 14d
Expand.
According to the vehicle-mounted dlternator using said structure, lattice is formed with the inside of resin cover plate,
The lattice extends and erected on the axis direction of axle in the circumferential, therefore can improve the overall rigidity of resin cover plate and strong
Degree, can especially improve impact resistance, and unrelated with the direction of impact, and without being impact resistance material by the material altering of resin cover plate
Material or thickening resin cover sheet thickness etc. and cause cost to increase.If existing resin cover plate is considered as benchmark, present embodiment
Resin cover plate only can be realized by changing metal die shape, and just can be real by carrying out slightly change to material usage
It is existing.
Lattice is additionally, since in the fore-and-aft direction projection from resin cover plate, there is curve shape, therefore can improve and divide
Intensity every portion itself, so as to improve the rigidity of resin cover plate.Further, since lattice is so that the metal member with potential difference
The mode spaced apart of device extends, therefore can prevent short circuit, and unrelated with the direction of impact.Further, since resin cover plate
Outside has concave shape or convex form, therefore can also improve the rigidity of resin cover plate.In addition, by making battery terminal covering part
Periphery and the periphery of adjuster connector covering part are concave shape so that battery terminal covering part, adjuster connector
The space expanded of covering part in itself, wire harness installation can be also improved.
Moreover, in the case where resin cover plate is made up of fire-retardant rank material, even if just in case causing short circuit by colliding
When generate spark, also can more reliably suppress the sprawling of the intensity of a fire.
More than, present disclosure is illustrated with reference to preferred embodiment, but those skilled in the art
Obviously various changes mode can be used under the basic fundamental thought of the present invention and enlightenment.
